Authenticated post meta disclosure via unchecked field key
Published Feb 5, 2024 · Updated Apr 8, 2026
Authorization bypass in Display custom fields in the frontend 1.2.1 and earlier allows remote authenticated users to read post meta. The vg_display_data shortcode accepts a user-controlled field key and retrieves the corresponding post_meta value without checking that the key is authorized for disclosure. Contributor-level access is required to supply the shortcode; the resulting exposure is limited to stored post metadata selected by the attacker.
